Inventor: AMEIKE TAKUYA
IPC: G03G15/08
Filed: 2021-03-31
Abstract: To provide a structure that achieves both movement of a shutter from a closed position to an open position and rotation of a conveyance member by a drive force supplied from a coupling, as well as enables rotation of the conveyance member to continue even after the shutter has moved from the closed position to the open position.SOLUTION: A toner cartridge 2 includes a damper 60. The damper 60 includes a damper shaft 62 and a damper case 61. The damper case 61 accommodates a damper oil. The damper oil serves as resistance to rotation of the damper shaft 62 against the damper case 61.
